Description

Technical Field

[0001] The present invention relates to the technical field of steel guardrails, in particular to a steel guardrail with an organic zinc epoxy powder coating and a production process thereof. Background Art

[0002] Guardrails, also known as safety barriers, are primarily used to protect personal safety and equipment in residential areas, highways, commercial areas, and public spaces. Guardrails are ubiquitous in our daily lives. The price per meter varies depending on the height of the guardrail. Guardrails are commonly made of steel materials such as stainless steel, round steel pipe, square steel pipe, corrugated steel sheet, and wire. Surface treatments include fully automatic electrostatic powder coating (also known as spray coating) or painting. In recent years, plug-in, prefabricated guardrails made of aluminum alloy have also become popular. The guardrail posts are secured to the ground with expansion bolts. They are typically installed in locations such as logistics corridors, around production equipment, in building corners, on the sides of doors, and along the edges of cargo platforms. They effectively mitigate damage to equipment and facilities caused by accidental impacts during the movement of handling equipment. Guardrails are manufactured from a variety of materials, including aluminum alloy, malleable cast iron (ductile iron), carbon steel (spray-coated or galvanized), stainless steel, plastic-coated steel, zinc-coated steel, PVC, and other metal guardrails.

[0003] Organic zinc epoxy powder coatings are often used in paint coating systems to protect facilities in highly corrosive environments. They are suitable for a variety of industries, such as offshore facilities, petrochemical plants, pulp and paper mills, bridges, power plants, etc. When spraying, all surfaces to be coated should be clean, dry, and free of contamination. Before painting, all surfaces should be judged and treated according to ISO8504:2000 standards. If grease is present, it should be removed according to SSPC-SP1 solvent cleaning requirements. The blasting treatment should be sandblasted according to Sa21 / 2 (ISO8501-1:2007) or SSPC-SP6 standards. If the steel surface oxidizes after sandblasting and before applying the epoxy zinc powder primer, the surface should be re-sandblasted to the specified visual standard.

[0004] However, the existing processing equipment has the following deficiencies:

[0005] In daily use, it is found that steel guardrails such as CN101265694A, the existing equipment mostly rely on the main body structure to absorb the kinetic energy generated by vehicle collision. During use, the main body is hit by external objects, which makes the kinetic energy generated by the collision high, causing serious damage to the vehicle and the guardrail. In addition, the existing facilities will be offset after the collision. After the collision, some drivers are unable to report the accident immediately, which prolongs the rescue time and reduces the protectiveness of the facilities.

[0006] Therefore, we proposed a steel guardrail with organic zinc epoxy powder coating and its production process in order to solve the above problems. Summary of the Invention

[0020] 1. The production process of the present invention is as follows: during processing, the raw materials are first hot-dip galvanized to play an electrochemical protective role to prevent corrosion of the substrate. After hot-dip galvanizing, the surface of the substrate is finished and degreased, and the substrate is cleaned twice. After cleaning, the surface is adjusted and the substrate is zinc-rich phosphating to enhance the adhesion between the coating and the surface of the substrate.

[0021] 2. The present invention sets a collision mechanism. When a vehicle hits the guardrail, the vehicle collides with the kinetic energy absorbing block, and the kinetic energy absorbing block is squeezed and deformed. At the same time, the kinetic energy absorbing block squeezes the air in the air cavity. The air in the air cavity cooperates with the kinetic energy absorbing block to absorb the impact force of the vehicle. When the air in the air cavity is squeezed, the air pressure sensing plate senses the increase in air pressure inside the air cavity.

[0022] 3. The present invention sets an assembly mechanism. When assembling the impact device, the H-shaped buckle frame is aligned with the hole groove reserved for the main pillar to push the kinetic energy absorbing block. The kinetic energy absorbing block pushes the H-shaped buckle frame. The H-shaped buckle frame squeezes the constraint cylinder. The constraint cylinder pushes the U-shaped rod. The U-shaped rod pushes the connecting buckle plate. The connecting buckle plate squeezes the limit spring. The limit spring is squeezed and deformed. At the same time, the constraint cylinder loses the constraint of the limit spring and moves. Then the H-shaped buckle frame is inserted into the reserved hole groove. Then the constraint cylinder loses the pressure of the H-shaped buckle frame. At the same time, the limit spring loses the pressure and rebounds. The constraint cylinder is pushed to reset during the rebound of the limit spring, and the H-shaped buckle frame is fixed. Then the assembly operation of the impact device is completed. By setting the assembly mechanism, the impact device can be quickly assembled on the guardrail, thereby reducing the installation cost and further increasing the assembly efficiency.

[0023] 4. The present invention provides a sealing mechanism. After the air pressure inside the air cavity is adjusted, the connecting sleeve is aligned with the air duct, and the round cover is pushed. The round cover pushes the connecting sleeve into the air duct. When the round cover is put on the surface of the air duct, the round cover is rotated, and the round cover gradually pushes the connecting sleeve. The connecting sleeve pushes the insertion pin. During the displacement process, the insertion pin contacts the water ring and breaks the water ring. The water source after the water ring is broken fills the gap between the connecting sleeve and the air duct, and the rubber pad is used to seal the air duct. By providing the sealing mechanism, the sealing performance of the impact device is improved, thereby reducing the probability of air outflow and further improving the stability of the air pressure inside the air cavity.

A sealing frame 719 is fixedly connected to the inner wall of the air cavity 712. The impact device 7 continuously reinforces the steel guardrail structure by utilizing the structural components of the device. Monitoring is performed through certain mechanisms, thereby enhancing the guardrail's protective performance and providing support for emergency alarms after a collision. This enables the device to reduce the intensity of the collision and perform subsequent processing.

[0038] according to Figure 6-7 As shown, the surfaces of the crossbeam 4 and the vertical rod 5 are both coated with an organic zinc epoxy powder coating, which has excellent corrosion resistance and impact resistance. The organic zinc epoxy powder coating can increase the structural strength of the steel guardrail and further improve the service life of the steel guardrail.

[0039] according to Figure 6-7 As shown, mounting housing 713 extends through kinetic energy absorbing block 711. PV panel 714 and battery 715 are connected by cables, as are signal transmission module 716 and data module 717. Signal transmission module 716 and battery 715 are also connected by cables, while data module 717 and battery 715 are also connected by cables. Kinetic energy absorbing block 711 can absorb the impact force generated when a vehicle collides with a guardrail and, in conjunction with air cavity 712, enhances kinetic energy absorption.

[0040] according to Figure 6-7As shown, a pressure sensing plate 718 is disposed through the mounting housing 713 and communicates with the inner wall of the air cavity 712. A flat cable connects the pressure sensing plate 718 to the battery 715 and to the data module 717. The pressure sensing plate 718 senses the air pressure within the air cavity 712, thereby cooperating with the data module 717 to monitor whether a collision with the guardrail has occurred.

[0041] according to Figure 8 As shown, the assembly mechanism 72 includes an H-shaped buckle frame 721, which is fixedly connected to the side surface of the kinetic energy absorbing block 711. A socket is provided on the surface of the main pillar 2, and a storage groove is provided on the inner wall of the main pillar 2 where the socket is provided. The inner wall of the main pillar 2 where the storage groove is provided is fixedly connected to a guide load-bearing frame 722, and the inner wall of the guide load-bearing frame 722 is fixedly connected to a limiting spring 724. The guide load frame 722 is provided to support and fix the position of the limit spring 724, and the moving direction of the U-shaped rod 725 can be restricted. At the same time, by providing the assembly mechanism 72, when assembling the impact device 7, the H-shaped buckle frame 721 is aligned with the hole groove reserved in the main pillar 2, and the kinetic energy absorbing block 711 is pushed. The kinetic energy absorbing block 711 pushes the H-shaped buckle frame 721, and the H-shaped buckle frame 721 squeezes the constraint cylinder 726. The constraint cylinder 726 pushes the U-shaped rod 725, and the U-shaped rod 725 pushes the connecting buckle plate 723. The connecting buckle plate 723 squeezes the limit spring 724, and the limit spring 7 24 is squeezed and deformed, and the restraining cylinder 726 loses the restraint of the limit spring 724 and moves. Then the H-shaped buckle frame 721 is inserted into the reserved hole groove, and then the restraining cylinder 726 loses the pressure of the H-shaped buckle frame 721. At the same time, the limit spring 724 loses the pressure and rebounds. The restraining cylinder 726 is pushed to reset during the rebound of the limit spring 724, and the H-shaped buckle frame 721 is fixed. Then the assembly operation of the impact device 7 is completed. By setting the assembly mechanism 72, the impact device 7 can be quickly assembled on the guardrail, thereby reducing the installation cost and further increasing the assembly efficiency.

[0042] according to Figure 8 As shown, a connecting plate 723 is fixedly connected to the side of the limit spring 724 near the H-shaped bracket 721. A U-shaped rod 725 is slidably connected to the inner wall of the guide load-bearing frame 722. A restraining cylinder 726 is fixedly connected to the side of the U-shaped rod 725 near the H-shaped bracket 721. The provision of the connecting plate 723 increases the contact area between the limit spring 724 and the U-shaped rod 725, thereby reducing malfunctions caused by insufficient contact area.

[0043] according to Figure 8As shown, an H-shaped buckle 721 is provided through the insertion hole, and there are two guide load-bearing frames 722, which are arranged symmetrically with respect to the H-shaped buckle 721. A connecting buckle plate 723 is fixedly connected to the surface of the U-shaped rod 725. A restraining cylinder 726 is provided through the receiving slot, abutting the inner wall of the H-shaped buckle 721 and slidingly connected to the inner wall of the guide load-bearing frame 722. The restraining cylinder 726 can cooperate with the limit spring 724 to clamp the H-shaped buckle 721, thereby fixing the position of the kinetic energy absorbing block 711.

[0044] according to Figure 9 As shown, a circular hole is formed on the surface of the kinetic energy absorbing block 711. A sealing mechanism 73 is provided on the inner wall of the circular hole of the kinetic energy absorbing block 711. The sealing mechanism 73 includes an air guide tube 731, which is fixedly connected to the inner wall of the circular hole. A sliding groove is formed on the surface of the air guide tube 731. A water ring 732 abuts the inner wall of the air guide tube 731 where the sliding groove is formed. A connecting sleeve 733 is sleeved on the inner wall of the air guide tube 731 where the sliding groove is formed. The air guide tube 731 can be used to adjust the air density within the air cavity 712 to improve the stability of the air cavity 712.

[0045] according to Figure 9 As shown, a pin 734 is fixedly connected to the side surface of the connecting sleeve 733, a rubber pad 735 is abutted against the surface of the connecting sleeve 733, and a round cover 736 is fixedly connected to the side of the connecting sleeve 733 away from the kinetic energy absorber 711.

The provision of the rubber pad 735 can enhance the sealing between the round cover 736 and the air guide tube 731.

[0047] The effect achieved by the entire mechanism is as follows: during processing, the raw materials are first hot-dip galvanized, and hot-dip galvanizing is used to provide electrochemical protection to prevent corrosion of the substrate. After hot-dip galvanizing, the surface of the substrate is finished and degreased, and the substrate is cleaned twice. After cleaning, the surface is adjusted, and the substrate is zinc-rich phosphating to enhance the adhesion between the coating and the substrate surface. After zinc-rich phosphating, it is cleaned again and dried. After the substrate is dried, the substrate is sprayed with an organic zinc epoxy powder coating to increase the corrosion resistance and impact resistance of the substrate. The coating is then cured. After curing, a polyester color coating is sprayed to improve resistance to ultraviolet rays and increase the self-cleaning ability of the substrate. After spraying, it is cured again, and then subsequent processing such as loading, welding and shaping can be carried out.

[0048] By setting up the collision mechanism 71, when the vehicle hits the guardrail, the vehicle collides with the kinetic energy absorbing block 711, and the kinetic energy absorbing block 711 is squeezed and deformed. At the same time, the kinetic energy absorbing block 711 squeezes the air in the air cavity 712. The air in the air cavity 712 cooperates with the kinetic energy absorbing block 711 to absorb the impact force of the vehicle. When the air in the air cavity 712 is squeezed, the air pressure sensing plate 718 senses that the air pressure inside the air cavity 712 increases, and the air pressure sensing plate 718 transmits the data to the data module 717. The data module 717 receives the data for calculation and processing. When the pressure exceeds the preset threshold, the data module 717 sends an instruction to the signal transmission module, and the signal transmission module then transmits the signal and issues an alarm, thereby reducing rescue time. By setting up the collision mechanism 71, the kinetic energy generated by the vehicle collision is reduced. At the same time, in the event of a major accident, an alarm can be processed in the first time, further increasing the probability of survival of the accident personnel.

[0049] At the same time, by setting the assembly mechanism 72, when assembling the impact device 7, the H-shaped buckle frame 721 is aligned with the hole groove reserved in the main pillar 2, and the kinetic energy absorbing block 711 is pushed. The kinetic energy absorbing block 711 pushes the H-shaped buckle frame 721, and the H-shaped buckle frame 721 squeezes the constraint cylinder 726. The constraint cylinder 726 pushes the U-shaped rod 725. The U-shaped rod 725 pushes the connecting buckle plate 723. The connecting buckle plate 723 squeezes the limit spring 724. The limit spring 724 is squeezed and deformed. At the same time, the constraint cylinder 726 loses the limit spring 726. 4 is displaced, and then the H-shaped buckle frame 721 is inserted into the reserved hole groove, and then the constraint cylinder 726 loses the pressure of the H-shaped buckle frame 721, and at the same time the limit spring 724 loses the pressure and rebounds, and the constraint cylinder 726 is pushed to reset during the rebound of the limit spring 724, and the H-shaped buckle frame 721 is fixed, and then the assembly operation of the impact device 7 is completed. By setting the assembly mechanism 72, the impact device 7 can be quickly assembled on the guardrail, thereby reducing the installation cost and further increasing the assembly efficiency.

[0050] When the air pressure inside the air cavity 712 is adjusted, the connecting sleeve 733 is aligned with the air guide tube 731 and the round cover 736 is pushed. The round cover 736 pushes the connecting sleeve 733 to insert into the air guide tube 731. When the round cover 736 is put on the surface of the air guide tube 731, the round cover 736 is rotated. The round cover 736 gradually pushes the connecting sleeve 733. The connecting sleeve 733 pushes the insertion pin 734. The insertion pin 734 contacts the water ring 732 during the displacement process and breaks the water ring 732. The water source after the water ring 732 is broken fills the gap between the connecting sleeve 733 and the air guide tube 731, and the rubber pad 735 is used to seal the air guide tube 731. By setting the closing mechanism 73, the sealing performance of the impact device 7 is higher, thereby reducing the probability of air outflow and further increasing the stability of the air pressure inside the air cavity 712.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
